Update: The US has agreed to let a video showing friendly fire incident
be made public. Read the AP
story here.

The British newspaper The Sun has made available a cockpit video showing
a friendly fire incident during the early phases of the Iraq War, in 2003,
when American planes fired accidentally on a British convoy, killing British
soldiers and a reporter.

CNN broadcast the video this morning. After the strike, one American
pilot said to the other "good hits." But when they learned from
their headquarters that they've struck a friendly target, one said to
the other "We're in jail," and one of the pilots also became
physically ill in his cockpit.

CNN reported that the video is being used in the course of a criminal
investigation in the United Kingdom.
